RBE v1.25 is ready to download! These are the changes: Added preliminary fan control for 5970 (EMC2103 fan controller). Big thanks to Diverge for making this possible! Added support for Radeon 5830, 5450 and 5570. Added signature file based overdrive hacking capability for 5xx0 cards. Thanks to Biker for extensive testing! Improved built-in hex editor search capability. Fixed another subvendor display issue, hopefully for good this time. Improved RAM interface detection. Fixed a rarely occurring bug (on mobile Radeon BIOSes only) regarding powerplay table. Added qualified error message if pre-2xx0 BIOS is detected. Fixed rare file opening issue. Updated WinFlash link. Fixed minor clock wizard issue. Added welcome message for first time users. Added feature to enable RivaTuner versions < v2.25 to cooperate with 5xx0 Radeons. Enjoy!
